Struct uefi_specs::uefi::nvram::EFI_VARIABLE_AUTHENTICATION_2

#[repr(C)]
pub struct EFI_VARIABLE_AUTHENTICATION_2 {
    pub timestamp: EFI_TIME,
    pub auth_info: WIN_CERTIFICATE_UEFI_GUID,
}

UEFI spec 8.2

Fields

timestamp: EFI_TIME

Components Pad1, Nanosecond, TimeZone, Daylight and Pad2 shall be set to 0. This means that the time shall always be expressed in GMT.

auth_info: WIN_CERTIFICATE_UEFI_GUID

Provides the authorization for the variable access. Only a CertType of EFI_CERT_TYPE_PKCS7_GUID is accepted.

Implementations

impl EFI_VARIABLE_AUTHENTICATION_2

pub const DUMMY: Self = _

A “dummy” header that doesn’t actually include a valid cert.

This header is used during parts of the pre-boot setup to inject TIME_BASED_AUTHENTICATED_WRITE_ACCESS from within the UEFI device itself.
